Hi Carl<P> I use 630 volt caps for replacement of paper types. For filters 450 volt electrolytics will replace originals. <P> Caps with these ratings don't cost much more than lower voltage types. Size will be smaller than your originals.<P>------------------<BR>Norm

Thanks for the responses.<BR>I did plan on using the 630v for the paper tubulars. Schematic shows a 330 plate voltage on the rectifier. Considered a 350v electrolytic, but will go with the 450v to be safe. Schematic shows these as 6, 7 and 8 mfd. Seem like low values for filter caps.<P>------------------<BR>Carl T
